Angle cocks heretofore in use have been uniform in design terminating in a hexagonal head or wrench-'hold threaded lto receive lthe end ot the train pipe to which it is attached. ln order to prevent. the loss of the angle cock railway cars are usually provided with angle cock holders engaging with the hexagonal heads. At the present time a neu7 type o1 angle cock is coming into use which diii'ers from the old in being provided with an auxiliary head projecting tothe rear ot the main head with an annular groove formed between the two. It is the theory that the use ol a U-bolt engaging with this groove will obviate the necessity of angle cock holders. Ve have found, however, that the neces- 1 sary clearance between the` train pipe andthe unthreaded auxiliary headv preventsl the etective clampingot the pipe by the U-bolt, which is an important featureof such holders so that they may not only prevent the loss of the angle cock 'when broken from the train pipe but also reduce the liability of such breakage. Thus the desirable functions of an angle cock holder are only partially secured in the new form et cock. Furthermore, the necessity ot replacement from stock on hand may at any time require the substitution of an angle cock of the oldform for one of the new or vice versa, and hence it is highly desirable to provide all cars with holders which are equally applicable to both forms..

It is the object of our invention to provide a transitional type of holder which will cooperate with the new or old form otangle cock and which will in either case torni an ei"- iective pipe clamp, and, further one'which will not require any longitudinal change in the position oIn the cock when substitution ot' one forni for the other is made while at the same time providing for the necessary adjustment '.t'or slightvvariation in the length of the train pipe.

In the accompanying drawings, whichilllustrate one form of angle cock holder made in accordance with our invention, Figure 1 is a side view partly in elevation and partly in section showing our holder applied to an angle cock of the old type; Figure 2 is a simila-r view showing it applied to anA angle cock ot thenew type; and Figure 3 is a section taken on the line 3-8 of Figure 2.

The body of the angle cock indicated at 5 an annular groove 9.

is providedin boththe old form, shownuin i Figurel, and the new form, shown in Figure 2, with a hexagonal head which engages r with the threaded end' of train pipe 7. In

the old form this head. for-ms the rear termiv v nation ot the cock, while-in the new forman auxiliary head 8 projects to the rear of the main head, the two heads being separatedV by Our holder comprises two separable members each provided at itsforward end with a part 10 substantially semi-hexagonal in Across section, the two parts cooperating to form a head pocket and each provided with a lip 11 engaging with the front tace of the head 6 to prevent the forward movement of the cock. The pocket formed by the parts 10 is divided into two sections by an inwardly'projecting-k ridge 12. The front section ofthe pocket receives the main head 6 when applied to either form of cock. The rear section performs no function when applied to the oldformrbut receives the auxiliary head 8 when applied'to j the new form., In additionv to forming aA firmly clamp the trainpipe. l These parts 13A terminate in flanges 111 flush with the Vperiphery of the pocket. yl3`or1ned between the 'flanges 14 and the rear end of the pocket is a Wide annular groove to receive the U-bolt. 15 by means oiz which the holder is secured to the supporting plate 16 which rbears against 14. lluts 17 threaded onthe ends ofthe bolt hold the device in position and the bolt ends are preferably split, as shown at 18, to form nut locking meansg'lhe wide groovein which the bolt is situated allows for adjustnient' to compensate i'or variations in the length of the pipe. It will be understood that Aone aceof the pocket and one of the flanges the supporting plate linay be secured to the j car in any well known Way.

Having fully described our invention, what we claim as new and desire to secureby Letters Patent of the United States is:

l; .An angle cock helder adapted to receive an angle cock having either a single or a double head, said holder lcomprising two compartments spaced from each other andibeing provided with a rib positioned to project into the space between the Aheads of a double headed angle cock.

2.V An angle cock holder having a pocket divided .into two parts by an inwardly projecting reinforcing rib and' adapted Yto re'- ceive and hold an angleeotkV having either a n single or doublel head', a supporting plate, ak Y train pipe clampingr part at the rear of said pocketand provided with ya groove, and a U-bolt'in ,saidV groove for securing the holder to the plate, said .groove being of greater width than the bolt to provide longitudinal adjustment. f e v 3.
